  1. 1. European Journal of Developing Country Studies, Vol.3 2007 ISSN(paper)2668-3385 ISSN(online)2668-3687 www.BellPress.org Evaluating Water Quality of Ganga River Within UttarPradesh State by Water Quality Index Analysis Using C++ Program Allaa M. Aenab (Corresponding author) PhD student, Environmental Engineering Department, Delhi Technological University (DTU), Delhi, India S. K. Singh Professor, Dean & HOD, Environmental Engineering Department, Delhi Technological University (DTU), Delhi, IndiaAbstractThe Ganga basin accounts for a little more than one-fourth (26.3%) of the country’s total geographical area andis the biggest river basin in India, covering the entire states of Uttarakhand (UK), Uttar Pradesh (UP), Bihar,Delhi, and parts of Punjab, Haryana, Himachal Pradesh, Rajasthan, Madhya Pradesh, and West Bengal. In thisstudy we chose Uttar Pradesh (UP) as maximum area in water pollution on Ganga River. For purpose of thisstudy we have 13 monitoring station along with Ganga River in UP state. The present study shows evaluation ofwater quality for Ganga River within UP using WQI analysis by C++ program. In the case of Ganga River theconcentrations of BOD, TH, PO4, NO3, EC and PH were found to be outside the acceptable range of WHOstandards.Keywords: Ganga River; Water Quality; WQI; C++ Program and River Evaluation1. IntroductionIndia’s water future is in danger if current trends in its use continue. The total annual surface water availability inthe country is estimated to be 1,869 billion cubic meter (bcm). Due to spatial-temporal variations, an estimated690 bcm of surface water is utilizable. Add to this 432 bcm of replenish able groundwater, and the total utilizablewater in the country is 1,122 bcm, which appears to be just about sufficient to meet our present needs. Since thetotal available water is more or less constant, rising demands due to population and economic growth will strainthe demand-supply balance. The Water Resources Group estimates that if the current pattern of demandcontinues, about half of the demand for water will be unmet by 2030 (WRG, 2009).Even the present situation is tenuous. Although at the macro level, demand and supply of water seem to balance,there are stark differences at the basin levels. Of the 20 major river basins in India, 14 are already water-stressedNearly three-fourth of India’s population lives in water-stressed regions (where per capita availability is less than2,000 cubic meters per year) of which one-third of the region is in water, scarce areas (where per capita wateravailability is less than 1,000 cubic meters per year). Climate change will further aggravate the problem bycausing erratic weather patterns. More extreme rates of precipitation and evapo-transpiration will cause moreinstances of droughts and floods, with disparate and complex effects at the sub-basin level (IIR, 2011).The river Ganga occupies a unique position in the cultural ethos of India. Legend says that the river hasdescended from Heaven on earth as a result of the long and arduous prayers of King Bhagirathi for the salvationof his deceased ancestors. From times immemorial, the Ganga has been Indias river of faith, devotion andworship. Millions of Hindus accept its water as sacred. Even today, people carry treasured Ganga water all overIndia and abroad because it is "holy" water and known for its "curative" properties.However, the river is not just a legend, it is also a life-support system for the people of India (WHO/UNEP,1997). It is important because: • The densely populated Ganga basin is inhabited by 37 per cent of Indias population. • The entire Ganga basin system effectively drains eight states of India. • About 47 per cent of the total irrigated area in India is located in the Ganga basin alone. • It has been a major source of navigation and communication since ancient times. • The Indo-Gangetic plain has witnessed the blossoming of Indias great creative talent.Water pollution is a major problem that is threatening the sustainability of water bodies. Punitive mechanisms,such as closure of industries for non-compliance, alone have not worked. Market-based mechanisms comprisingtaxes on polluting industries, and tax concessions for adoption of abatement technologies, should supplement thecurrent legislation. Mechanisms such as green ratings should also be promoted and eventually be made 1

Objectives and ApproachThe objective envisaged for this study is critical evaluation of present status of water environment and servicesin Ganga River, India. For this purpose, the relevant information has been collected and analyzed as below: 1. Evaluation of Ganga River water quality. 2. Refine or create Ganga River specific water quality standards pursuant to International standards including development of appropriate reference conditions. 3. To provide an early warning system for downstream users about adverse water quality conditions.3. Materials and Methods3.1 Study AreaThe Ganga River has significant economic, environmental and cultural value in India. Rising in the Himalayasand flowing in to the Bay of Bengal, the river traverses a course of more than 2,500 km through the plains ofnorth and eastern India. The Ganga basin – which also extends into parts of Nepal, China and Bangladesh –accounts for 26 per cent of India‘s landmass, 30 per cent of its water resources and more than 40 per cent of itspopulation. The Ganga also serves as one of India‘s holiest rivers whose cultural and spiritual significancetranscends the boundaries of the basin (NGRBA, 2011).Ganga is a perennial river which originates as a stream called “Bhagirathi” from Gaumukh in the Gangotriglacier at 30 ° 55 N, 79 ° 7 E, some 4100 m above mean sea level. Ganga river basin is the largest among riverbasins in India and the fourth largest in the world, with a basin (catchment area) covering 8, 61,404 sq km. It hasa total length of 2,525 km, out of which 1,425 km is in Uttaranchal and UP, 475 km is in Bihar and 625 km is inWest Bengal. Already half a billion people live within the river basin, at an average density of over 500 per sqkm, and this population is projected to increase to over one billion people by the year 2030 (Rakesh, 2007).The Ganga basin is one of the most populous regions on Earth, home to 450 million people at an average densityof over 550 individuals per square kilometre. In the delta zone this rises to over 900 per square kilometre. As aresult, there is strong demand and competition for natural resources, especially water for domestic use andirrigation, and barrages regulate most of the basin tributaries. Fisheries along the river are of considerableeconomic value and their output makes a major contribution to regional nutritional needs (WWF, 2010).There are some 30 cities, 70 towns, and thousands of villages along the banks of the Ganga. Nearly all of thesewage from these population centres – over 1.3 billion litres per day – passes directly into the river, along withthousands of animal carcasses, mainly cattle. Another 260 million litres of industrial wastewater, also largelyuntreated, are discharged by hundreds of factories, while other major pollution inputs include runoff from themore than 6 million tonnes of chemical fertilizers and 9,000tonnes of pesticides applied annually within the basin. According to Hindu mythology, the Ganga River camedown to Earth from the heavens. Today, the river symbolizes purification to millions of Hindus who believe thatdrinking or bathing in its waters will lead to moksha, or salvation. Many Hindus keep water from the Ganga inglass bottles as a sacred relic, or for use in religious ceremonies. The river becomes the final resting place forthousands of Hindus, whose cremated ashes or partially burnt corpses are placed in the river for spiritual rebirth(WWF, 2010).3.2 Critical stretches of the Ganga:In different stretches the holy Ganga River is posed with different challenges (see fig.1) (CSE, 2008). • In the upper reaches (Himalayan segment) numerous hydel projects (commissioned as well as planned) threaten the river ecosystem by depriving it off the environmental flows • In the stretch beyond this (till Patna) the growing cities and industrial clusters have increased the pollution load discharged into the river. Loss of assimilative capacity has worsened the pollution woes of the river. • In the stretch beyond Patna, the river is relatively clean. But growing cities and lack of assimilation is making the river dirtier.Fig. 2 shows images for Ganga River pollution within India. 2

European Journal of Developing Country Studies, Vol.3 2007 ISSN(paper)2668-3385 ISSN(online)2668-3687 www.BellPress.org3.3 River Water PollutionA river is defined as a large natural stream of water emptying into an ocean, lake, or other body of water andusually fed along its course by converging tributaries. Rivers and streams drain water that falls in upland areas.Moving water dilutes and decomposes pollutants more rapidly than standing water, but many rivers and streamsare significantly polluted all around the world.A primary reason for this is that all three major sources of pollution (industry, agriculture and domestic) areconcentrated along the rivers. Industries and cities have historically been located along rivers because the riversprovide transportation and have traditionally been a convenient place to discharge waste. Agricultural activitieshave tended to be concentrated near rivers, because river floodplains are exceptionally fertile due to the manynutrients that are deposited in the soil when the river overflows.3.3.1 Source of pollutionFarmers put fertilizers and pesticides on their crops so that they grow better. But these fertilizers and pesticidescan be washed through the soil by rain, to end up in rivers. If large amounts of fertilizers or farm waste drain intoa river the concentration of nitrate and phosphate in the water increases considerably.Algae use these substances to grow and multiply rapidly turning the water green. This massive growth of algae,called eutrophication, leads to pollution. When the algae die they are broken down by the action of the bacteriawhich quickly multiply, using up all the oxygen in the water which leads to the death of many animals (CWC,2011).Chemical waste products from industrial processes are sometimes accidentally discharged into rivers. Examplesof such pollutants include cyanide, zinc, lead, copper, cadmium and mercury. These substances may enter thewater in such high concentrations that fish and other animals are killed immediately.Sometimes the pollutants enter a food chain and accumulate until they reach toxic levels, eventually killingbirds, fish and mammals.Factories use water from rivers to power machinery or to cool down machinery. Dirty water containingchemicals is put back in the river. Water used for cooling is warmer than the river itself. Raising the temperatureof the water lowers the level of dissolved oxygen and upsets the balance of life in the water. People aresometimes careless and throw rubbish directly into rivers.3.3.2 River water quality & Environmental factorsRiver water quality is highly variable by nature due to environmental conditions such as basin lithology,vegetation and climate. In small watersheds spatial variations extend over orders of magnitude for most majorelements and nutrients, while this variability is an order of magnitude lower for major basins. Standard riverwater for use as reference is therefore not applicable. As a consequence natural waters can possibly be unfit forvarious human uses, even including drinking.There are three major natural sources of dissolved and soluble matter carried by rivers: the atmospheric inputs ofmaterial, the degradation of terrestrial organic matter and the weathering of surface rocks. These substancesgenerally transit through soil and porous rocks and finally reach the rivers. On their way, they are affected bynumerous processes such as recycling in terrestrial biota, recycling and storage in soils, exchange betweendissolved and particulate matter, loss of volatile substances to the atmosphere, production and degradation ofaquatic plants within rivers and lakes etc. As a result of these multiple sources and pathways, the concentrationsof elements and compounds found in rivers depend on physical factors (climate, relief), chemical factors(solubility of minerals) and biological factors (uptake by vegetation, degradation by bacteria). The mostimportant environmental factors controlling river chemistry are (CWC, 2011): • Occurrence of highly soluble (halite, gypsum) or easily weathered (calcite, dolomite, pyrite, olivine) minerals. • Distance to the marine environment which controls the exponential decrease of ocean aerosols input to land (Na+, CIP, SO4P2, and Mg+2). • Aridity (precipitation/runoff ratio) which determines the concentration of dissolved substances resulting from the two previous processes. • Terrestrial primary productivity which governs the release of nutrients (C, N, Si, K). • Ambient temperature which controls, together with biological soil activity, the weathering reaction kinetics. • Uplift rates (tectonism, relief) Stream quality of unpolluted waters (basins without any direct pollution 3

The objective of an index is to turn complex waterquality data into information that is understandable and useable by the public. This type of index is similar to theindex developed for air quality that shows if it’s a red or blue air quality day. The use of an index to "grade"water quality is a controversial issue among water quality scientists. A single number cannot tell the whole storyof water quality; there are many other water quality parameters that are not included in the index. The indexpresented here is not specifically aimed at human health or aquatic life regulations. However, a water indexbased on some very important parameters can provide a simple indicator of water quality. It gives the public ageneral idea the possible problems with the water in the region (Mitchell, 2000). Table 1 showing Water QualityIndex Ranges (Hameed, 201; Brown, 1970).3.4.3 Water Quality Index CalculationThe WQI was calculated using the standards of drinking water quality recommended by the World HealthOrganization (WHO) (Aenab, 2012). The weighted arithmetic index method was used for the calculation of WQIof the surface water. Further, quality rating or sub index (qn) was calculated using the following expression(Brown, 1970).qn= 100 [Vn – Vio]/[Sn – Vn](Let there be n water quality parameters and quality rating or sub index (qn) corresponding to nth parameter is anumber reflecting the relative value of this parameter in the polluted water with respect to its standard, maxi-mum permissible value).qn = Quality rating for the nth water quality parameterVn = Estimated value of the nth parameter at a given sampling point.Sn = Standard permissible value of the nth parameter.Vio = Ideal value of nth parameter in pure water (i.e. 0 for all other parameters except the parameter pH andDissolve Oxygen (7.0 and 14.6 mg/L respectively).Unit weight was calculated by a value inversely pro- portional to the recommended standardvalue Sn of the corresponding parameter.Wn = K/SnWn unit weight for the nth parameters.Sn = standard value for the nth parametersK = constant for proportionality.The overall WQI was calculated by aggregating the quality rating with the unit weight linearly.WQI = ∑ qnWn / ∑ Wn3.4.4 Parameter SelectionThere are so many different parameters that can be used to measure water quality. From a global perspective it isimportant to outline a few consistent measurements that can be measured easily, by all, on a regular basis, andthat are clearly correlated to biodiversity in aquatic environments. The specific parameters used to assess waterquality were chosen based on findings reported in the primary literature.3.5 Application of C++ Program3.5.1. IntroductionC++ is a statically typed, free-form, multi-paradigm, compiled, general-purpose programming language. C++ issometimes called a hybrid language. It is regarded as an intermediate-level language, as it comprises a combi- 4

It was developed by Bjarne Stroustrupstarting in 1979 at Bell Labs as an enhancement to the C language. Originally named C with Classes, thelanguage was re- named C++ in 1983 (Stroustrup, 2010). C++ is one of the most popular programminglanguages [(PLP, 2010),(TPCI, 2011)] with application do- mains including systems software, applicationsoftware, device drivers, embedded software, high-performance server and client applications, and entertainmentsoftware such as video games (C++, 2010). Several groups provide both free and proprietary C++ compilersoftware. C++ has greatly influenced many other popular programming lan- guages, most notably C# and Java.After years of deve- lopment, the C++ programming language standard was ratified in 1998 as ISO/IEC14882:1998. The standard was amended by the 2003 technical corrigendum, ISO/ IEC 14882:2003. The currentstandard extending C++ with new features was ratified and published by ISO in September 2011 as ISO/IEC14882:2011 (informally known as C++11) [(ISO, 2011), (MPPL, 2011)].3.5.2. Algorithms and StepsIn my work using language C++ under window to execution, and perform some steps to implementation thisprogram (Aenab, 2012): • Create Project File consist of number of files. • Create dialog boxes that perform to dialog with users. • Read and input Data to system for all stations from users. • Select type of process from menu (Water Quality Index). • Execution algorithm and calculate mathematics for all process after enter data. • Display Result with high speed (Less than 1 second). As is shown in table 2.4. ResultsThe status of water quality of Ganga River in Uttar Pradesh is presented in Table 2. It is observed from the tablethat, the parameters values it was BOD (6.5 mg/l), TH (421 mg/l), NO3 (11.7 mg/l), PO4 (0.068 mg/l), EC (1200mg/l) and PH (9) all parameters values out of the WHO standard values.5. ConclusionsWater Quality Index (WQI) in total 137.7924 for the year 2011 and this make it under category more than 100,so it means water quality of Ganga River in Uttra Pradesh unsuitable.ReferencesNGRBA, 2011.
